WebI am now studying phasors and my teacher told us that when you find in an exercise, for example the current and that current is for example \$ -2 + 3j \$ , then, when you want to find the angle, which is \$ \theta = arctan(-1.5) \$, you have to add to the result angle 180 degrees to find the final angle.
